Subject: staging: vt6655: remove unused variable
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=0c596a31ec3c3db2fe5ee78e9f46ae2e0bcb9aa0;p=openwrt%2Fstaging%2Fblogic.git

staging: vt6655: remove unused variable

This patch removes a variable that was simply used to
store the return value of a function call before
returning it.

The issue was detected and resolved using the following
coccinelle script:

@@
identifier len,f;
@@

-int len;
 ... when != len
     when strict
-len =
+return
        f(...);
-return len;
